$PECIFICATION forming' part of Letters Patent No. 587,617, dated August 3, 1897.

Application filed 'Tune 9, 1896. Serial No. 594,874. (No model.)

T 0 all whom i 77m1/ 0071108772,.-

Be it known that I, IRA E. STUMP, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Carpet-Sweepers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which- Figure 1 is a perspective view showing a portion of the cover broken away. Fig. 2 is a Vertical section showingone end of the sweeper and illustrating the relative positions of the brush-cylinder shaft and fan-shafts. Fig. 3 is an end view showing the spring for holding the traveling Wheels in' dotted lines. Fig. 4 is a detached view of the end bar, showing the spring and disks for holdingsaid spring in proper position. Fig. 5 is a view showing one end of one of the traveling-wheel shafts and illustrating a traveling wheel 10- oated thereon and a portion of the spring connected to the shaft. Fig. 6 is a transverse section of the sweeper. Fig. 7 is a transverse section of one of the end bars and its different parts. Fig. 8 is a detached view of one of the Springs.

The present invention has. relation to carpet-sweepers; and it consists in the difierent parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar figures of reference indicate corresponding parts in all the figures of the drawlngs.

In the accompanying drawings, 1 represents the end pieces of the sweeper proper, which end pieces may be substantially of the form shown. To the end pieces 1 is securely attached in any convenient and well-known manner the cover 2, said cover being arranged substantially as shown in Fig. 1. To the end pieces 1 or their equivalents is journaled the brush-cylinder shaft 3, to which shaft are securely attached the wheels 4, which wheels are preferably located upon the outer sides of the end pieces 1, as illustrated in Fig. 1. To the shaft 3 are securely attached the disks 5, to which disks are attached the -brush-bars 6, said brush-bars being provided with the brushes 7.

To the peripheries of the disks 5 are properly journaled the fan-shafts 8 by means of suitable boxing, such as 9, said shafts being located between the brush-bars 6, substantially as illustrated in Figs. 1 and 6, and revolve in unison with the brush-bars. To the shafts 8 are-attached in any convenient and well-known manner the fan-blades 10, said fan-blades being formed of such a width that they will .clear the shaft 3 as they rotate with the axillary rotation of the shafts 8, said axillary rotation being imparted to the shafts 8, as hereinafter described.

Upon the inner face or faces of the end pieces l are located the disks 11, said disks being so arranged that the peripheries of the friction-wheels 12 will press or bear against the peripheries of the disks 11 and impart rotary motion to the wheels 12 and the fanshafts 8, in addition to the rotarymotion of said shafts 8 around the brush-cylinder shaft 3. It will be understood that the disk 11 is fixed to the end piece 1, or, if desired, said disk may be formed integral with the end piece and does not have any'rotary motion.

The traveling wheels 13 are located substantially as shown in Figs. 1 and 3, and, as shown, they are so arranged that their peripherics will press or bear against the disks or wheels 4, thereby imparting rotary motion to the disks or wheels 4 and to the brushcylinder proper as the carpet sweeper is pushed or pulled over the carpet or'other object designed to be swept.

To the extended `arms 14 are securelyattaohed in any convenient and well-known manner the bars 15, to which bars is journaled the brush-cylinder shaft 3. The inner faces of the bars 15 are provided with the groovesl, said grooves being for the purpose of assisting in holding the springs 17 in proper position with reference to said bars 15. For the purpose of preventing the Springs froin becoming accidentally displaced the disks or buttons 18 are provided,whioh disks or buttons are held in proper position by means of the screws 19 or their equivalents. The Springs 17 are provided with the rightangled portions 20, which right-angled por- IOO tions are entered into proper recesses 21, formed in the ends of the shafts 22, upon which shafts 22 are loosely mounted the traveling Wheels 18. The springs 17 are for the purpose' of normally holding the traveling` Wheels 13 in such a position that they will press or bear against the wheel 4.

The apertures 23, through which the shafts 22 pass, are formed somewhat larger in cliameter than the diameter of the shafts, thereby allowing the body of the carpet-sweeper, together with its different attachments, to be pressed toward the carpet or other surface over which the sweeper is traveling, thereby producing greater pressure of the brushes upon the surface being swept.

It will be understood that the fan-blades 10 should be formed of such a width that their edges will not strike the carpet as they are carried around With the lnaish-cylinder, or, in other words, the end of brushes 7 should be extended a short distanee beyond the outer limit of the fan-blades 10. The object and purpose of providing the fan-blades and locating the same as shown is to create a sufi'icient amount of blast to blow the dust into the dust-receptacles.

In the drawings the dust-receptacles or pans are not illustrated, inasmuch as it Will be understood that the ordinary pans are to be provided and should be located in the 01'- dinary manner. v

It will be understood that by providin g the springs 17 the traveling Wheels 13 will at all times press or bear against the Wheels 4, regardless of the pressure placed upon the sweeper proper by means of the Operatinghandle 2-1. r The operating-handle 21 is pivotally connected to the ends 1 by means of the bail 25, which bail may be substantially of the form shown in Fig. 1. For the purpose of protecting the ends 1 and at the same time providing a means foi` better connecting i the bail 2'5 metal plates, such as 2G,- are provided, which metal plates are attached to the ends 1 in any convenient and Well-known manner.

Having fully described my invention, What I claim as new, and desire to secure byLetters Patent, is

1. The combination of a sweeper-frame, a brush-cylinder journaled therein, means for rotating the brush-cylinder, shafts provided p with fan-blades journaled on or near the periphery of the brush-cylinder, andmeans for imparting an axial motion to said shafts upon the rotation of the brush-cylinder, substan-` tiall y as described.

2. The combination of a sWeeper-frame, i
